"Fox News Sunday" anchor Chris Wallace said President Trump's rhetoric on immigration will be questioned if the Democrats retake the House of Representatives in Tuesday's midterm elections.

On Thursday, just days before voters head to the polls, Trump announced that, in response to what he called the "crisis at our southern border" and a surge of fraudulent asylum claims, his administration would require asylum-seekers to "lawfully present themselves" at a port of entry.

Trump's planned "comprehensive" executive order on immigration-related matters -- which he said would come next week -- appears to be in response to a caravan of thousands of migrants headed toward the U.S. border.

On "America's Newsroom" Friday, Wallace said Trump has made immigration the major issue heading into midterms, and he wondered if it wouldn't be more effective to campaign on the booming economy.

He noted that the October jobs report revealed 250,000 jobs added, a 3.7 percent unemployment rate and wage growth at the fastest rate since 2009.

"He says all those things, but that isn't the focus, that isn't the headline coming out of this president and his rallies," Wallace said.

He acknowledged that Trump proved the "know-it-alls" in the media wrong two years ago with his election victory, but if Republicans don't have similar success this year, the president will "second-guessed" by many in his party.

"If his plan works, people will say, 'Well, you know what? He's the genius.' But if they lose the House, there's gonna be a lot of second-guessing that he should have run on a more economic-based campaign."

House Intelligence Committee Chairman Adam Schiff of California said that "people have suffered enough" because of President Trump and that a real leader would re-open the part of the government that has been shuttered since December.
